Fluid simulation not working after parenting to animated object
The blob is a cube. It look like a blob because the subdivision surface modfier. The domain is not a fluid source or a fluid object. The domain is the border of your simulation. So you have to increase the domain's size to include the jars and add a fluid object inside it instead your current domain object. Don't move the domain. Add fluid>>obstacle to the jars.
